She had been treated at Twin Cities Community Hospital in Templeton for minor injuries she suffered in the Sunday night crash south of Paso Robles that led to the death of CHP officer Brett Oswald, 47, of Atascadero.

The CHP has scheduled a news conference at 3:30 p.m. in San Luis Obispo.

UPDATE

The CHP officer who died late Sunday after being hit by a car earlier in the evening has been identified as Brett Oswald, 47. He was a 21-year veteran of the CHP.

"Officer Oswald was a real hero; one of California's bravest. He risked his life day in and day out to protect the safety of Californians," Gov. Arnold Schwarzenegger said in a statement Monday.

Oswald was the one of two CHP officers killed Sunday, and the fifth in two months.

Another CHP officer was struck and killed in Barstow early Sunday. Two motorcycle officers were fatally struck in incidents earlier this month in Los Angeles and Redlands, and a CHP pilot died in a plane crash in Imperial County last month.

Original story:

A CHP officer died late Sunday from injuries he suffered when he was hit by a car earlier in the evening south of Paso Robles.

Just after 6:30 p.m., a woman driving a copper-colored Toyota Corolla along South River Road — between the two intersections with Spanish Camp Road — turned a corner at high speed and lost control, according to the CHP.

The officer — who works out of the agency’s Templeton office — had been outside his patrol car, checking on an abandoned vehicle that had been reported just before 6 p.m., according to Sheriff’s Department spokesman Rob Bryn.

Someone had reported to authorities that the car was left on the roadside in such a way that it would probably get hit after nightfall, according to the CHP.

The officer was waiting for a tow truck to come and move it when he was struck, Bryn added.

For reasons unknown, the Toyota’s driver did not see the CHP car in the roadway, he said.

The Toyota hit the rear of the officer’s patrol car, sending it forward to where it hit the officer, Bryn said.

The officer flew into the air, landing on the Toyota, which stopped in the northbound lane of South River Road.

He was treated at Twin Cities Community Hospital in Templeton.

A convoy of law enforcement units escorted a hearse van to the Chapel of the Roses in Atascadero, which had been summoned to the hospital, according to CHP dispatches.

The driver of the Toyota did not appear to be injured.

Authorities are not disclosing the names of anyone involved pending more investigation, Bryn said.

No information was made available on whether arrests or citations would be issued.

South River Road was closed to traffic after the crash, and the scene was “locked down,” with all access to the area barred, according to the CHP.
